ECG voltage criteria and Romhilt-Estes point scores positively correlate with left ventricular mass index and are significantly increased in hypertensive patients with concentric and eccentric hypertrophy.
ECG criteria may inform LVH assessment in hypertension; leaves open prospective validation before guiding practice.
The exact diagnosis of left ventricular hypertrophy (LVH) is very important in the treatment of hypertension. The purpose of our study is to determine the relationship between left ventricular remodeling patterns and electrocardiography (ECG) findings in hypertensive patients. We divided 137 patients into four groups according to left ventricular mass index (LVMI) and the relative wall thickness: normal, concentric remodeling, concentric hypertrophy, eccentric hypertrophy. LVH on the ECG was defined by three ECG criteria: Sokolow-Lyon voltage criteria, Cornell voltage criteria and Romhilt-Estes point score. LVH on the echocardiography was defined by LVMI. The prevalence of ECG LVH was increased in concentric hypertrophy and eccentric hypertrophy group. The QRS voltages by Sokolow-Lyon voltage criteria (r = 0.494, P = 0.002) and Cornell voltage criteria (r = 0.628, P < 0.001), and Romhilt-Estes point score (r = 0.689, P < 0.001) were positively correlated with LVMI. Also, the QRS voltages and point scores were significantly increased in the concentric hypertrophy and eccentric hypertrophy group with increased LVMI. The QRS voltage and Romhilt-Estes point scores were positively correlated with LVMI. The QRS voltages and Romhilt-Estes point scores were also increased in the left ventricular remodeling groups with increased LVMI.

Sun Young Choi (2015) conducted a case-control in Hypertension with left ventricular remodeling (n=137). Electrocardiography (ECG) vs. Echocardiography was evaluated on Diagnostic accuracy (AUC) of Cornell voltage criteria for left ventricular hypertrophy (AUC 0.722, 95% CI 0.622-0.808, p=<0.001). Electrocardiography QRS voltages and Romhilt-Estes point scores were positively correlated with left ventricular mass index and significantly increased in hypertensive patients with concentric and eccentric hypertrophy.
